Comparison HP Victus 16-s1000 [16-s1012ua] vs Acer Nitro 17 AN17-42 [AN17-42-R7XK]

Diagonal size of laptop display.

The larger the screen, the more convenient the laptop for watching high-definition movies, modern games, working with large-format graphic materials, etc. Large screens are especially important for multimedia and gaming models. On the other hand, the diagonal of the display directly affects the size and cost of the entire device. So if portability is key, it makes sense to pay attention to relatively small solutions; especially since most modern laptops have video outputs like HDMI or DisplayPort and allow connection of large-format external monitors.

In light of all this, the actual maximum for laptops these days is 17"(17.3"); however larger devices (18") reappeared at the beginning of 2023. The standard option for general purpose laptops is 15"(15.6"), less often 16", a diagonal of 13"(13.3") or 14" is considered small by the standards of such And smaller screens can be found mainly in specific compact varieties of laptops — ultrabooks, 2 in 1, transformers, netbooks; among such devices there are solutions for 12 ", 11" and even 10" or less.

— Glossy. A glossy surface improves the overall picture quality: other things being equal, the picture on such a screen looks brighter and more colorful than on a matte one. On the other hand, pollution is very noticeable on such a surface, and in bright external lighting, a lot of glare appears on it, which can greatly interfere with viewing. Therefore, instead of the classic gloss, laptops are increasingly using an anti-reflective version of such a coating (see below). Nevertheless, this option still does not lose popularity: it is somewhat cheaper than the “anti-glare”, and in soft, relatively dim lighting, it can even provide a more pleasing image to the eye.

— Matte. Matte finish is inexpensive and does not form glare even from fairly bright lighting. On the other hand, the picture on such a screen is noticeably dimmer than on a similar glossy display. However, this moment can be compensated by various design solutions (primarily a good margin of brightness); so this option can be found in all categories of modern laptops — from low-cost models for working with documents to top gaming configurations.

— Glossy (anti-glare). A variation on the glossy finish described above, designed to reduce glare from external light sources. Such screens really glare noticeably less than traditional glossy ones (or even do not give glare at all); at the same...time, in terms of image quality, they are at least superior to matte ones. So it is this type of coating that is most popular nowadays.

Screen response time to a control signal — in other words, the time between the receipt of such a signal on the matrix and the switching of pixels to a given mode.

Theoretically, the lower the response time, the better the screen handles with dynamic scenes, the higher the frame rate on it can be achieved. At the same time, it is worth noting that almost all modern matrices have sufficient response speed to effectively process the classic frame rate of 60 Hz — and, recall, it is quite enough for most cases. So paying attention to this parameter makes sense, first of all, if you are purchasing an advanced gaming model, the screen of which operates at a frame rate of more than 60 Hz. In other cases, the response time is often not indicated at all.

The frame rate supported by the laptop screen. In fact, in this case we are talking about the maximum frequency; the actual frame rate may be lower than this value, depending on the content being displayed — but not higher.

Theoretically, the higher the frame rate, the smoother the movement on the screen will look, the less moving objects will be blurred. In fact, the situation is such that even in relatively modest modern laptops, 60 Hz matrices are installed — in general, this is quite enough for the human eye, since a further increase in speed ( 90 Hz and higher) does not significantly improve the visible “picture”. However, in high-end gaming and multimedia models designed for demanding users, higher values — 120 Hz, 144 Hz, 165 Hz and even higher, namely 240 Hz and 300 Hz.

The colour gamut of the laptop matrix according to the Rec.709 colour model or according to sRGB.

Colour gamut describes the range of colours that can be displayed on the screen. It is indicated as a percentage, but not relative to the entire variety of visible colours, but relative to the conditional colour space (colour model). This is due to the fact that no modern screen is able to display all the colours visible to humans. However, the larger the colour gamut, the wider the screen's capabilities, the better its colour reproduction.

Specifically, sRGB and Rec.709 are the most popular of today's colour models; they have the same range and differ only in the scope (sRGB is used in computers, Rec. 709 is used in HDTV). Therefore, the closer the colour gamut is to 100%, the more accurately the colours on the screen will match the colours that were originally intended by the creator of the film, game, etc. At the same time, note that such accuracy is not particularly needed in everyday use — it critical only for professional work with colour; and even in such cases, it is more convenient to buy a separate monitor with a wide colour gamut for a laptop, rather than looking for a laptop with a high-quality (and, accordingly, expensive) matrix.

The laptop supports AMD FreeSync technology and its more advanced varieties (FreeSync Premium, FreeSync Premium Pro). Here are more details about them:

– AMD FreeSync. This function is found only in models equipped with discrete AMD graphics cards. It serves to match the frame rate of the screen and the frame rate of the incoming signal so that the frequencies match. This allows you to avoid flickering, jerking and other image defects that occur due to signal desynchronization. This function is especially useful for games where the frame rate of the video signal can “float” depending on the load on the graphics core; in fact, most laptops with FreeSync are specifically gaming laptops.

– AMD FreeSync Premium. An intermediate option between the core AMD FreeSync technology and the advanced FreeSync Premium Pro implementation. The Premium version does not have HDR support (unlike Pro), but it works at the same frame rate (at least 120 fps at a resolution of 1920x1080) and uses LFC low frame rate compensation technology.

– FreeSync Premium Pro. The most advanced version of FreeSync technology, formerly known as AMD FreeSync 2 HDR. As the original name suggests, one of the highlights of this edition is HDR support. FreeSync Premium Pro claims a frame rate of at least 120 fps at Full HD resolution, as well as a low frame rate compensation (LFC) function. According to the creators, FreeSync Premium Pro works es...pecially well in games; and many modern games are initially created to work with this technology.

NVIDIA video cards use a similar technology called G-Sync.

Laptop support for NVIDIA G-Sync technology.

This feature is only found on models equipped with discrete NVIDIA graphics cards. It is used to match the frame rate of the screen and the frame rate of the signal arriving at it — so that these frequencies match. This avoids flickering, twitching, and other image artifacts that can occur due to out-of-sync. This feature is especially useful for games where the frame rate of the video signal can "float" depending on the load on the graphics core; in fact, most laptops with G-Sync are specifically for gaming.

A similar solution for AMD video cards is called FreeSync.

In laptops, the image processed by a discrete video card first passes through the graphics built into the CPU, and only then is transmitted to the display. The MUX Switch on the motherboard of gaming laptop models allows you to choose between using integrated or discrete graphics. One of its advanced varieties is the Advanced Optimus intelligent system, which works in conjunction with video adapters from NVIDIA. It allows you to literally choose on the fly the most suitable GPU for data processing, depending on the intensity of the tasks being performed.

A device for working with removable memory cards. Usually, it looks like a characteristic slot right on the laptop case, into which the media is inserted. There are different standards for memory cards, a list of compatible standards is indicated in the note to this item. It is worth noting here that for modern laptops it is almost mandatory to support the SD format and its modifications — SD HC, often also SD XC; other options may also be envisaged, but they have not received such distribution. Anyway, this feature is convenient because memory cards are widely used in other types of electronics: for example, SD is the generally accepted standard in digital cameras, and microSD (compatible with SD slots through simple adapters) is used in smartphones. Accordingly, the presence of a card reader greatly facilitates the exchange of data between a laptop and external devices.
